Social distancing and wearing a mask when necessary.
Everyone is trying to be outside in this era of the coronavirus. The Centers for Disease Control and Prevention (CDC) published guidance on how to do so in public outdoor spaces, see Visiting Parks and Recreational Facilities.
The bottom line is that you cannot just throw caution to the wind -- just because you are outside. As it is indoors, size matters. Large crowds should be avoided! You can still enjoy summer and do it safely. Review the guidelines -- and enjoy being outdoors!
